Abstract	The exact alignment of accelerator components is of crucial importance for the production of low emittance beams. Once a beam-line section is set up, a supplementary correction of misalignments implies the knowledge of its magnitude which is difficult to determine using conventional adjusting instruments. An excellent alternative to measure existing misalignments of accelerator components is to vary machine parameters and compare the behaviour of the beam with results obtained from a simulation. It is obvious that time consuming particle tracking programs are not appropriate to reach this aim. Regarding computing time, the on-line simulation code V is advantageous compared to other beam dynamics programs. The theoretical basis of V-Code, the "Ensemble Model", consists of selfconsistent equations for the ensemble parameters that are derived from the Vlasov equation. The requirement to simulate misalignments such as offsets and tilts led to the development of the ALIGNMENT UTILITY which utilizes the solver of V-Code. The new utility enabled us to investigate the beam-line alignment of the TESLA Test Facility injector. This contribution presents the theoretical background and an illustrating example of the optimization process.
